FLUSHlNG-CUSPIDOR.

Specification of Letters Patent.

Patented Oct. 10, 1905-.

Application filed May 12, 1904. Renewed August 17, 1905- Serial No. 274,643.

To all whom it may concern:

Be it known that 1, JOHN WV. CooPnR, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Flushing-Cuspidors, of which the following is a specification.

Spittoons of the flushing type designed for dentists receive solid mattersuch as cotton, paper, fragments of filling, tooth structure, and the like and are liable to choke and overflow unless watched and the obstructing matter removed.

This invention, among other things, is designed to construct a spittoon of the class aforesaid with an overflow to prevent its running over should the outlet in the bottom become stopped, said overflow and adjuncts being of peculiar and novel formation.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.

Vhile the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of afiushingspittoon embodying the invention. Fig. 2 is a central vertical section of the device. Fig. 3 is a top plan view of the article. Fig. 4 is a section similar to Fig. 2, showing a modification.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The body of the spittoon is indicated at 1 and is of bowl form and is provided at a'central point of the bottom with a tubular projection 2, forming an outlet. An annular water-duct 3 surrounds the upper portion of the spittoon and is connected to a service-pipe for supplying water by means of the connection 4, which may be a short length of lead pipe or other tubing capable of being bent into the form substantially as shown. hen the spittoon is constructed of porcelain, earthenware, vitreous material, vulcanite, or the like, it is provided near its edge with a trough 5, in which the annular water-duct 3 is fitted. A

boss or extension 6 communicates with the bottom of the trough 5 and receives the metal connection 7 coupling the pipe 4 to the part 3. A clamp-nut 8 is threaded upon the connection 7 and confines a packing 9, by means of which a tight joint is obtained between the parts 5 and 7.

The annular water-duct 3 is a hollow ring, preferably of metal and of a shape to snugly fit the trough 5, and is provided at its top side with a series of threaded openings in which thimbles 10 are fitted and receive nozzles 11, which are curved and arranged approximately at a tangent to the annular duct 3. By having the nozzles 11 fitted to the annular waterduct 3 in the manner stated they may be readily removed, soas to clear them of any obstructing matter. Should any part of the duct become obstructed, one or more of the thimbles 10 may be removed, thereby providing openings of sufiicient size to admit of the introduction of one or more instruments for removing the obstructing matter. The nozzles 11 are curved and arranged in such a manner as to deliver jets of water against the crown of an annular guard 12 in a way to prevent noise and to distribute the water upon the inner side of the guard, whereby it will trickle downward and discharge upon the sides of the spittoon, so as to flow toward the outlet in the bottom thereof in straight lines without being carried around in a spiral passage. As a result of the direct flow of the water from the rim portion of the spittoon to the outlet matter discharged into the receptacle is carried off by a direct and straight path and not caused to circle around the sides of the spittoon, as would be thecase if the water moved in a spiral passage. The guard 12 besides acting as a deflector for the jets of water also serves to house the nozzles to cover the water-duct and to prevent water from splashing over the upper edge of the spittoon. In cross-section the guard 12 is of arch form and is supported by means of an outer bead 13 near the upper edge of the part 1.

At a point in its circumferential length the annular water-duct 3 is interrupted by a partition in which a vertical opening 14 is formed, said opening flaring at its upper end and covered by means of screen-cloth 15 or a reticulated plate through which water may freely pass, said parts 14 and 15 constituting the overflow. A short pipe 16, similar to the connection 4, is coupled to the part 14 and is adapted to be connected with the waste (not shown) in any determinate way. A boss or extension 17 projects from the trough portion 5 at a point preferably diametrically opposite to the boss or extension 6 and receives a thimble or short length ol. pipe 18, which is connected to the part 3 in a manner similar to the part 7. The pipe 16 is coupled to the thimble 18 in the usual way, and a tight joint is i'naintained between the parts 1'7 and 18by a packinggland and clamp -nut corresponding to the parts 9 and S, cooperating with the thimblc 7.

A short pipe 19 is fitted within the exten sion 3 and is outwardly flanged at its upper end, as shown at 20, and a packing 21 is conlined between the tlange and the body 1, the latter being recessed to admit of the flange 20 coming about flush with the inner side of the spittoon, so as not to offer any projecting part for the lodgment of matter. The lower end of the pipe 19 is externally threaded and extends beyond the part 2 and receives the nipple or fitting 22. The hosepipe (not shown) for carrying off the water from the spittoon is coupled to the nipple 22. A holder23 is confined between the extension 2 and the nipple 22, a tight joint being 01 tained by means of a washer 2st. The holder 23 is of annular form and is provided at opposite points with extensions 25, which are notched in their outer ends and to which are bolted or fastened by machine-screws plates 26, notched in their inner edges, the notches in the parts 25 and 26 unitedly forming open ings to receive the lower ends of the respective pipe connections t and 16. By having the parts 4t and 16 and the cooperating elements located at diametrically opposite points the weight is equalized upon the spittoon, thereby lessening the tendency of the article to sag at any one point.

Fig. 4C shows a construction admitting of the device being stamped or pressed from sheet material, the body of the spittoon being continuous from center to rim and having an annular portion 27, soldered or otherwise connected to the outer portion of the bowl and of such construction as to form an annular space corresponding to the annular waterduct 3 and with which the pipes a and 16 connect in the manner substantially as hereinbefore specified. This construction admits of the spittoon being formed of sheet metal, which may be either spun or pressed and linished in any manner to present apleasing appearance.

Having thus described the invention, what is claimed as new is- 1. In a flushing-spittoon, the combination of an annular water-duet arranged near the upper edge of its rim and provided with outlets, a guard extending over the said waterduct and serving to deflect the jets of water issuing therefrom, and an overflow extended through the annular water-duct and communicating with the upper portion of the spit' toon, substantially as set forth.

2. In a flushing-spittoon, the combination of an annular water-duct near the upper edge of the spittoon, a supply-pipe communicating with said water-duct and arranged to one side of the spittoon, and an overflow-pipe located at the diametrically opposite side of the spittoon and having a portion extended through said annular water-duct and communicating with the spittoon at a point above said water-duct, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
